You begin by laying a blue backed prediction card face down on the table. Then you display both the front and back of a red deck. With the help of a spectator, the magic begins. You ask the spectator to give a number of their own choosing. They now use that number to select a card. The remainder of the deck is placed off to the side and the prediction is now turned over to reveal that it matches the spectator's card! But it's not a perfect match because the selection has a red back and the prediction is blue. You respond, "No problem!" With a snap of your fingers both cards now have blue backs! The audience is impressed, but you explain that the prediction you can understand, but where all the other cards went is another matter. With that, you turn over the remainder of the deck to reveal all the faces are now totally blank! This is a real triple whammy!
